It certainly is worth a try, but the new sirens ($140?) beep when you operate the door locks.
Yeah as far as I have searched the new siren from internet, its cheapest there in North America. Maybe could find one also from Germany but I can't handle germanies language

And here in Finland you can't find anything under 300e
But yeah I'm going to open the old one tomorrow cause' I have killer hangover rigth now and I don't have the security torx.
I put couple of photos here also If someone doesn't know the location of alarm module...
